Abstract
Description
本說明書關於ATR抑制劑在治療癌症中之用途,其特徵在於,將ATR抑制劑投與至之前已經接受免疫療法之患者,該ATR抑制劑係例如,4-{4-[(3R )-3-甲基𠰌啉-4-基]-6-[1-((R )-S -甲基磺醯胺基)環丙基]嘧啶-2-基}-1H-吡咯并[2,3-b]吡啶(AZD6738,賽拉雷澤替博(ceralasertib),下文稱為化合物 (I) 或其藥學上可接受的鹽)。說明書還關於治療之方法,該等方法包括將ATR抑制劑投與至之前已經接受免疫療法的患者;ATR抑制劑用於生產用於治療之前已經接受免疫療法的患者中的癌症的藥物之用途;包含一定量的多種ATR抑制劑的藥物組成物在癌症療法中之用途;以及包含此類藥物組成物的套組(kit)。 (I)The present specification relates to the use of an ATR inhibitor in the treatment of cancer, characterized in that the ATR inhibitor is administered to a patient who has previously received immunotherapy, the ATR inhibitor being, for example, 4-{4-[(3 R )- 3-Methylpyrin-4-yl]-6-[1-(( R ) -S -methylsulfonamido)cyclopropyl]pyrimidin-2-yl}-1H-pyrrolo[2,3 -b]pyridine (AZD6738, ceralasertib, hereinafter referred to as compound (I) or a pharmaceutically acceptable salt thereof). The instructions also pertain to methods of treatment comprising administering an ATR inhibitor to a patient who has previously received immunotherapy; use of the ATR inhibitor for the manufacture of a medicament for the treatment of cancer in a patient who has previously received immunotherapy; Use of pharmaceutical compositions comprising amounts of multiple ATR inhibitors in cancer therapy; and kits comprising such pharmaceutical compositions. (I)
ATR係絲胺酸/蘇胺酸蛋白激酶並且是磷脂醯肌醇3-激酶相關激酶(PIKK)家族的成員。在正常的DNA複製過程中,ATR被募集在停止的複製叉處,該等複製叉如果不修復的話會發展成雙股斷裂。在單股DNA損害或雙股斷裂的切除後,ATR也被募集至覆蓋有複製蛋白A(RPA)的單股DNA。ATR的募集和激活導致細胞週期在S-階段停滯、同時DNA被修復並且停止的複製叉分解,或者核碎裂並且進入計劃性細胞死亡(細胞凋亡)。ATR is a serine/threonine protein kinase and is a member of the phosphatidylinositol 3-kinase-related kinase (PIKK) family. During normal DNA replication, ATR is recruited to stalled replication forks that, if not repaired, develop into double-strand breaks. ATR is also recruited to single-stranded DNA covered with replication protein A (RPA) following excision of single-stranded DNA damage or double-stranded breaks. Recruitment and activation of ATR results in cell cycle arrest in S-phase, the breakdown of replication forks, where DNA is repaired and stalled, or nuclear fragmentation and entry into programmed cell death (apoptosis).
因此,預期ATR抑制劑造成依賴ATR進行DNA修復的腫瘤細胞(例如,ATM-缺陷型腫瘤)之生長抑制。除了此類單療法活性,還預計ATR抑制劑(藉由抑制ATR-依賴性DNA修復過程)加強細胞毒性DNA損害劑的活性和放射療法療效(當它們聯合使用時)。Thus, ATR inhibitors are expected to cause growth inhibition of tumor cells that rely on ATR for DNA repair (eg, ATM-deficient tumors). In addition to such monotherapy activity, ATR inhibitors (by inhibiting ATR-dependent DNA repair processes) are also expected to potentiate the activity of cytotoxic DNA damaging agents and the efficacy of radiation therapy (when they are used in combination).
示例性ATR抑制劑包括AZD6738,一種相對於首先在WO 2011/154737中揭露的其他PIKK家族成員具有優良的選擇性的有效ATR抑制劑。該化合物正在被開發,作為患有依賴ATR功能進行DNA修復的疾病(例如絲胺酸/蘇胺酸-特異性蛋白激酶(ATM)缺陷型腫瘤)的患者之口服抗腫瘤劑。Exemplary ATR inhibitors include AZD6738, a potent ATR inhibitor with excellent selectivity over other PIKK family members first disclosed in WO 2011/154737. This compound is being developed as an oral antineoplastic agent for patients with diseases that depend on ATR function for DNA repair, such as serine/threonine-specific protein kinase (ATM)-deficient tumors.
ATR抑制劑正在被研究用於對抗各種形式的癌症,包括惡性黑色素瘤。黑色素瘤由皮膚中稱為黑素細胞的產色素細胞發展而來並且是皮膚癌中最危險之形式。在2015年,有310萬人患有活性黑色素瘤,這導致59,800人死亡(Vos等人,Lancet [柳葉刀]388 , 1545-1602);而在2020年,美國癌症學會預計將局部診斷約100,000新病例,約7,000例死亡。ATR inhibitors are being studied to combat various forms of cancer, including malignant melanoma. Melanoma develops from pigment-producing cells in the skin called melanocytes and is the most dangerous form of skin cancer. In 2015, 3.1 million people had active melanoma, which resulted in 59,800 deaths (Vos et al., Lancet [Lancet] 388 , 1545-1602); in 2020, the American Cancer Society expects local diagnoses of approximately 100,000 New cases, about 7,000 deaths.
目前黑色素瘤的標準護理係基於一線免疫療法,例如使用免疫檢查點抑制劑,例如,納武單抗(nivolumab)或派姆單抗(pembrolizumab)。具有可訴性突變的患者(例如具有BRAF突變的患者)可以接受靶向藥劑。患者可以接受數種不同的免疫療法線,但是一旦它不再有效,標準的化學療法(像雙重卡鉑和紫杉醇或單藥劑紫杉醇)可用於繼續治療。然而,對化學療法的反應通常是差的,約20%患者反應於雙重化學療法並且僅約5%的患者反應於紫杉烷。因此,迫切需要能夠用於治療不再適合免疫療法的抗性癌症(像黑色素瘤)的其他方法。The current standard of care for melanoma is based on first-line immunotherapy, such as the use of immune checkpoint inhibitors such as nivolumab or pembrolizumab. Patients with an actionable mutation, such as those with a BRAF mutation, can receive targeted agents. Patients can receive several different lines of immunotherapy, but once it is no longer effective, standard chemotherapy (like dual carboplatin and paclitaxel or single-agent paclitaxel) can be used to continue treatment. However, response to chemotherapy is generally poor, with about 20% of patients responding to dual chemotherapy and only about 5% responding to taxanes. Therefore, additional approaches that can be used to treat resistant cancers that are no longer amenable to immunotherapy, like melanoma, are urgently needed.
令人驚奇地,已經發現,ATR抑制劑,例如AZD6738在之前已經接受用免疫療法治療的癌症患者(包括黑色素瘤患者)中特別有效,其中高比例的此類個體反應於後續ATR抑制。因此,已經接受先前的免疫療法的患者已經被鑒定為用ATR抑制劑(例如AZD6738)進行治療的靶群體。而且,ATR抑制似乎還增加對免疫療法具有抗性的癌症對用紫杉烷(例如紫杉醇)的化學療法的反應率。Surprisingly, it has been found that ATR inhibitors, such as AZD6738, are particularly effective in cancer patients, including melanoma patients, who have been previously treated with immunotherapy, with a high proportion of such individuals responding to subsequent ATR inhibition. Therefore, patients who have received prior immunotherapy have been identified as a target population for treatment with ATR inhibitors such as AZD6738. Moreover, ATR inhibition also appears to increase the response rate of immunotherapy-resistant cancers to chemotherapy with taxanes (eg, paclitaxel).
不希望受理論的約束,據信,用免疫療法治療的癌症可以變得對ATR抑制劑治療敏感,甚至在免疫療法本身在控制疾病方面停止發揮效力之後也是如此。Without wishing to be bound by theory, it is believed that cancers treated with immunotherapy can become sensitive to ATR inhibitor treatment even after immunotherapy itself ceases to be effective in controlling the disease.
本說明書之目的是提供ATR抑制劑(例如AZD6738)尤其是在治療癌症中之新用途。The purpose of this specification is to provide novel uses of ATR inhibitors such as AZD6738, especially in the treatment of cancer.

在任何實施方式中,在用「係」或「可為」來定義材料或元素時,「係」或「可為」可以意指該材料或元素「由該材料或元素組成」或「基本上由該材料或元素組成」。In any embodiment, where "is" or "may" are used to define a material or element, "is" or "may" may mean that the material or element "consists of" or "substantially" consists of that material or element".
當提到「在一些實施方式中……」時,可以存在某個元素,該元素可以存在於說明書的任何部分中的合適實施方式中,而不僅僅是說明書的相同部分或文本區域中的合適實施方式中。When referring to "in some implementations..." there may be an element that is present in the appropriate implementation in any part of the specification, not just in the same part of the specification or where appropriate in the text area in the implementation.
當一個特徵「選自」具體的清單,則該特徵可以選自由具體的替代選擇組成的清單(即那些替代選擇並且不包含其他的清單)。When a feature is "selected" from a specific list, the feature may be selected from a list of specific alternatives (ie, those alternatives and no other list).
請求項係實施方式。治療用途 The claim item is the implementation. therapeutic use
在一個實施方式中,提供了一種用於治療癌症之ATR抑制劑,其中該ATR抑制劑被投與至之前已經接受免疫療法的患者。In one embodiment, there is provided an ATR inhibitor for use in the treatment of cancer, wherein the ATR inhibitor is administered to a patient who has previously received immunotherapy.
在一個實施方式中,提供了一種治療需要此種治療的人類或動物患者的癌症之方法,該方法包括將ATR抑制劑投與至之前已經接受免疫療法的患者。In one embodiment, there is provided a method of treating cancer in a human or animal patient in need of such treatment, the method comprising administering an ATR inhibitor to a patient who has previously received immunotherapy.
在一個實施方式中,提供了ATR抑制劑在製造用於治療癌症的藥物中之用途,其中該藥物被投與至之前已經接受免疫療法的患者。In one embodiment, there is provided the use of an ATR inhibitor in the manufacture of a medicament for the treatment of cancer, wherein the medicament is administered to a patient who has previously received immunotherapy.
在一個實施方式中,提供了一種用於治療癌症的藥物組成物,其包含ATR抑制劑和藥學上可接受的賦形劑,其中該藥物組成物被投與至之前已經接受免疫療法的患者。免疫療法 In one embodiment, there is provided a pharmaceutical composition for the treatment of cancer comprising an ATR inhibitor and a pharmaceutically acceptable excipient, wherein the pharmaceutical composition is administered to a patient who has previously received immunotherapy. Immunotherapy
如果患者「之前已經接受免疫療法」,這包括已經成功或未成功用免疫療法治療、使得他們的癌症分別反應於或未反應於治療的患者。之前已經接受免疫療法的患者可以由於治療失敗已經停止先前的治療,其中免疫療法對癌症的生長或疾病的健康影響不是或不再係積極控制的。在這樣的治療失敗時,癌症可以被描述為對免疫療法具有抗性。當癌症的一些固有的特徵阻止免疫療法起作用時,發生原發性抗性,然而,當在免疫療法治療過程中癌症變得具有抗性時,發生獲得性抗性,也稱為繼發性抗性。一些患者可以接受免疫療法作為輔助療法。對輔助的免疫療法復發的患者也可能被認為對免疫療法具有原發性抗性。If a patient has "previously received immunotherapy," this includes patients who have been successfully or unsuccessfully treated with immunotherapy, making their cancer respond or fail to respond, respectively. A patient who has previously received immunotherapy may have discontinued previous treatment due to treatment failure, where the immunotherapy's health effects on the growth of the cancer or the disease are not or are no longer actively controlled. When such treatments fail, the cancer can be described as resistant to immunotherapy. Primary resistance occurs when some inherent characteristic of the cancer prevents immunotherapy from working, however, acquired resistance, also known as secondary, occurs when the cancer becomes resistant during immunotherapy treatment resistance. Some patients can receive immunotherapy as adjunctive therapy. Patients who relapse to adjuvant immunotherapy may also be considered primary resistant to immunotherapy.
在一些實施方式中,患者的癌症對免疫療法可能具有抗性。In some embodiments, the patient's cancer may be resistant to immunotherapy.
在一些實施方式中,患者對免疫療法具有原發性抗性。在一個實施方式中,原發性抗性根據癌症免疫療法學會(SITC)建議被定義為具有 ≥ 6週的免疫療法藥物暴露和在進展之前小於6個月的進行性疾病或穩定疾病的最佳反應。In some embodiments, the patient is primary resistant to immunotherapy. In one embodiment, primary resistance is defined according to Society for Cancer Immunotherapy (SITC) recommendations as having ≥ 6 weeks of immunotherapy drug exposure and less than 6 months of progressive disease or stable disease prior to progression reaction.
在一些實施方式中,患者對免疫療法具有獲得性抗性。在一些實施方式中,獲得性抗性根據SITC建議被定義為具有 ≥ 6週的免疫療法藥物暴露和在進展之前超過6個月的完全反應、進行性疾病或穩定疾病的最佳反應。In some embodiments, the patient has acquired resistance to immunotherapy. In some embodiments, acquired resistance is defined according to SITC recommendations as having ≥ 6 weeks of immunotherapy drug exposure and a complete response, progressive disease, or best response with stable disease more than 6 months prior to progression.
「免疫療法」係利用患者自己的免疫系統治療疾病,例如癌症。其包括刺激患者的免疫系統的天然防禦,所以更好的是發現和攻擊身體內的有害物質(例如癌細胞),以及投與像免疫系統成分一樣起作用的藥物以便恢復或改善免疫系統工作方式以保護身體(例如發現和攻擊癌細胞)。"Immunotherapy" uses a patient's own immune system to treat diseases, such as cancer. It includes stimulating the patient's immune system's natural defenses, so better to find and attack harmful substances in the body (such as cancer cells), and administering drugs that act like components of the immune system to restore or improve the way the immune system works To protect the body (eg find and attack cancer cells).
在一些實施方式中,免疫療法可以包括用免疫檢查點抑制劑治療、嵌合抗原受體T-細胞療法、用細胞介素治療、用免疫調節劑治療、用癌症疫苗治療、用單株抗體治療、和/或用溶瘤病毒治療。In some embodiments, immunotherapy can include treatment with immune checkpoint inhibitors, chimeric antigen receptor T-cell therapy, treatment with interferons, treatment with immunomodulatory agents, treatment with cancer vaccines, treatment with monoclonal antibodies , and/or treatment with an oncolytic virus.
「檢查點抑制劑」包括任何阻斷免疫檢查點的物質:免疫系統的關鍵調控劑,當受到刺激時,其能抑制對免疫刺激的免疫反應。一些癌症能藉由刺激免疫檢查點靶來保護它們自身不受攻擊,所以,使用能阻止抑制檢查點的檢查點療法,從而恢復免疫系統功能。A "checkpoint inhibitor" includes any substance that blocks immune checkpoints: key regulators of the immune system that, when stimulated, suppress the immune response to immune stimulation. Some cancers protect themselves from attack by stimulating immune checkpoint targets, so using checkpoint therapy that blocks inhibition of checkpoints can restore immune system function.
示例性檢查點抑制劑包括PD-1抑制劑(例如派姆單抗[Keytruda®]、納武單抗[Opdivo®]、西米普利單抗(cemiplimab)[Libtayo®]、斯巴達珠單抗(spartalizumab)[PDR001]、卡瑞利珠單抗(camrelizumab)[SHR1210]、信迪利單抗(sintilimab)[IBI308]、替雷利珠單抗(tislelizumab)[BGB-A317]、特瑞普利單抗(toripalimab)[JS 001]、AMP-224或AMP-514、PD-L1抑制劑(例如阿特珠單抗(atezolizumab)[Tecentriq®]、阿維魯單抗(avelumab)[Bavencio®]、德瓦魯單抗(durvalumab)[Imfinzi®]、KN035、CK-301、AUNP12、CA-170或BMS-986189和CTLA-4抑制劑(例如伊匹單抗(ipilimumab)[Yervoy®]或曲美木單抗(tremelimumab))。Exemplary checkpoint inhibitors include PD-1 inhibitors (eg, pembrolizumab [Keytruda®], nivolumab [Opdivo®], cemiplimab [Libtayo®], spartazhul spartalizumab [PDR001], camrelizumab [SHR1210], sintilimab [IBI308], tislelizumab [BGB-A317], Ripilimab (toripalimab) [JS 001], AMP-224 or AMP-514, PD-L1 inhibitors (eg, atezolizumab [Tecentriq®], avelumab [ Bavencio®], durvalumab [Imfinzi®], KN035, CK-301, AUNP12, CA-170 or BMS-986189 and CTLA-4 inhibitors such as ipilimumab [Yervoy®] ] or tremelimumab).

整體研究設計:
該研究由兩部分組成,每一部分評估當AZD6738與紫杉醇組合給藥時的安全性和耐受性。使用AZD6738的口服配製物。第一部分(A部分)與紫杉醇組合;在患有晚期實體惡性腫瘤的患者中,40 mg AZD6738 OD的開始劑量被遞增至達到最大耐受劑量,如劑量限制性毒性所定義的。我們進行了一系列的生檢以便基於出現的PK和PD之間的關係進一步探索在所選的一個或多個劑量下AZD6738的生物學活性。第二部分(B部分)係平行的PK擴展群組,其中週期0第1天給予AZD6738、(7天AZD6738洗脫期)第8至第21天單一療法(在紫杉醇組合之前),隨後從週期1開始伴有每週給予紫杉醇的組合療法。我們使該等群組的數量和劑量為彈性的以便當PK數據出現時我們能做出調整。第一部分係主要的臨床試驗。我們根據由其他正在進行的使用AZD6738的研究產生的數據做出改變以招募最小或最大數量的患者。在每一個群組中獨立地操作劑量遞增;然而,該等群組的數量和劑量將隨著PK數據的出現而接受改變。 Overall Study Design: The study consisted of two parts, each evaluating the safety and tolerability of AZD6738 when administered in combination with paclitaxel. Oral formulation of AZD6738 was used. The first part (Part A) was in combination with paclitaxel; in patients with advanced solid malignancies, the starting dose of 40 mg AZD6738 OD was escalated to the maximum tolerated dose, as defined by dose-limiting toxicities. We performed a series of biopsies to further explore the biological activity of AZD6738 at the selected dose or doses based on the emerging relationship between PK and PD. The second part (Part B) was a parallel PK expansion cohort in which AZD6738 was administered on day 1 of
A 部分
:我們進行了I期試驗以確定在患有難治癌症的患者中,AZD6738與固定劑量的紫杉醇組合給藥時的最大耐受劑量(MTD)。在A部分中我們使用滾動6設計。治療時間表如下。開始方案(每4週):40 mg OD給藥AZD6738,3週進行/1週停止;在第1天、第8天、第15天,紫杉醇80 mg/m2。這部分係與標準劑量的紫杉醇組合;在轉移性實體癌患者中,40 mg AZD6738 OD的開始劑量被遞增至達到最大耐受劑量。每個週期由4週組成。劑量遞增的決定係根據直到在第2週期的第1天投與研究藥物的時間收集的安全性和耐受性數據的評估做出的。選擇DLT評估期係因為導致在此類研究(血液學酶、胃腸道酶、肝臟酶)中劑量遞增停止的主要毒性有望在這段時期內呈現。AZD6738的劑量和/或時間表將由SRC定義。採用至少3個並且最多6個患者的群組大小(「滾動六設計」)以藉由減少對在DLT評估期變得不可評估的患者的後期代替的需要(同時不損害安全性數據的收集)來改善患者與接近假設治療劑量的群組的自然增長率。患者的總數量取決於所需的劑量調節的次數。該等患者具有視需要匹配的生檢以評估腫瘤的相關藥效學生物標誌物,並且進一步探索在該等劑量下的耐受性、安全性和藥物動力學活性。採用最多10個患者(最少2個患者)的群組大小。匹配的生檢定義為在基線、第7天和隨後疾病進展時的樣本(對於該試驗係視需要的)。 Part A : We conducted a phase I trial to determine the maximum tolerated dose (MTD) of AZD6738 in combination with fixed-dose paclitaxel in patients with refractory cancer. In Part A we use a scroll 6 design. The treatment schedule is as follows. Starting regimen (every 4 weeks): AZD6738 at 40 mg OD, 3 weeks on/1 week off; paclitaxel 80 mg/m2 on
B 部分
:平行PK拓展B部分用於評估藥物動力學。在開始B部分的第1週期(4週)之前,我們進行4週(第0週期)的單劑量AZD6738的藥物動力學評估。B部分係與標準劑量的紫杉醇組合;40 mg AZD6738 OD的起始劑量被遞增至藉由A部分獲得的最大耐受劑量。治療時間表如下。開始方案(每4週):40 mg OD給藥AZD6738,3週進行/1週停止;在第1天、第8天、第15天,紫杉醇80 mg/m2。 Part B : Parallel PK Expansion Part B was used to assess pharmacokinetics. Before starting cycle 1 (week 4) of Part B, we performed a pharmacokinetic evaluation of a single dose of AZD6738 for 4 weeks (cycle 0). Part B was combined with standard doses of paclitaxel; the starting dose of 40 mg AZD6738 OD was escalated to the maximum tolerated dose obtained with Part A. The treatment schedule is as follows. Starting regimen (every 4 weeks): AZD6738 at 40 mg OD, 3 weeks on/1 week off; paclitaxel 80 mg/m2 on

研究治療: AZD6738藉由口服片劑與紫杉醇組合投與。對於所有劑量,患者從服藥前至少2小時至服藥後至少1小時必須禁食(僅可飲用水)。AZD6738由阿斯利康研發中心(AstraZeneca R&D)作為單瓶片劑提供。組合藥劑由當地來源提供(直接地或有償的當地供應)。根據由阿斯利康研發中心制定的藥品生產品質管制規範和當地管理指南來製備標籤。所有研究藥物在合適的儲存條件下保存在安全的地方。瓶上的AZD6738和組合藥劑產品標籤指定合適的儲存方式。 Study Treatment: AZD6738 was administered by oral tablet in combination with paclitaxel. For all doses, patients must fast (only water) from at least 2 hours before and at least 1 hour after. AZD6738 is offered as a single vial tablet by AstraZeneca R&D. Combinations are provided from local sources (direct or paid local supply). Labels were prepared in accordance with Good Manufacturing Practice and local regulatory guidelines developed by AstraZeneca R&D. All study drugs are kept in a safe place under appropriate storage conditions. AZD6738 and the combination drug product label on the bottle specifies appropriate storage.
AZD6738的起始劑量/時間表係在4週(28天)的週期中,21天每天40 mg OD、隨後7天治療停止。研究以A部分(紫杉醇組合)開始,其中使用所選的每日一次40 mg AZD6738的起始劑量。對於所有劑量,患者從服藥前至少2小時至服藥後至少1小時必須禁食(僅可飲用水)。在第一週期之前,患者在第一天(第0週期第1天)接受單次劑量以評估PK,然後6天不接受研究藥物。然後,在第1週期第1天、第8天和第15天投與紫杉醇,同時從每個為期28天的週期的第1天至第21天再引入每天一次AZD6738。根據出現的安全性和耐受性數據決定其他部分的起始劑量/時間表。The starting dose/schedule of AZD6738 is based on a 4-week (28-day) cycle of 40 mg OD per day for 21 days followed by 7 days of treatment discontinuation. The study started with Part A (paclitaxel combination) with a selected starting dose of AZD6738 of 40 mg once daily. For all doses, patients must fast (only water) from at least 2 hours before and at least 1 hour after. Prior to Cycle 1, patients received a single dose on Day 1 (Day 1 of Cycle 0) to assess PK and then received no study drug for 6 days. Then, paclitaxel was administered on
響應於安全性、耐受性、藥物動力學和出現的非臨床數據,增加或降低在隨後的群組中的每日劑量、劑量頻率和給藥時間表。劑量遞增和遞減遵循以下方案,根據以下邏輯: (a) 如果在3名可評估的患者的群組中沒有觀察到劑量限制性毒性(DLT),那麼可以進行劑量遞增。在對來自最少3名可評估的患者的數據進行審查後,將允許劑量增加。 (b) 如果在3名或更多名可評估的患者的組中一名患者經歷了DLT,那麼該群組將被擴展到包括6名可評估的患者。如果在6名可評估的患者的完整群組中只觀察到一例DLT,那麼可以進行劑量遞增。 (c) 如果在至多6名可評估的患者的群組中2名或更多名患者經歷DLT,那麼不論入組患者的數量如何,將認為劑量不被耐受並且對該群組的招募和劑量遞增將停止。可以考慮更低的中間劑量(遞減)以便更好地定義MTD。The daily dose, dose frequency, and dosing schedule in subsequent cohorts were increased or decreased in response to safety, tolerability, pharmacokinetics, and emerging nonclinical data. Dose escalation and decrement follow the following schedule, according to the following logic: (a) If no dose-limiting toxicity (DLT) is observed in the cohort of 3 evaluable patients, then dose escalation may be performed. Dose escalation will be permitted after review of data from a minimum of 3 evaluable patients. (b) If one patient in a cohort of 3 or more evaluable patients experienced DLT, the cohort will be expanded to include 6 evaluable patients. If only one DLT is observed in the complete cohort of 6 evaluable patients, dose escalation can be performed. (c) If 2 or more patients in a cohort of up to 6 evaluable patients experience DLT, then regardless of the number of patients enrolled, the dose will be considered intolerable and recruitment and Dose escalation will stop. A lower intermediate dose (decrease) can be considered to better define the MTD.
在來自一個群組的最後一名可評估的患者完成給藥與隨後群組中開始給藥之間沒有最少時間期限的要求。沒有患者內劑量遞增。在研究的劑量遞增期過程中每次劑量水平之後,研究者評估AZD6738的安全性和耐受性和藥物動力學以決定下一劑量和/或時間表。There is no minimum time period required between the completion of dosing by the last evaluable patient from a cohort and the initiation of dosing in subsequent cohorts. There were no intra-patient dose escalation. Following each dose level during the dose escalation phase of the study, the investigator evaluates the safety and tolerability and pharmacokinetics of AZD6738 to determine the next dose and/or schedule.
基於出現的數據,由SRC做出以改變下一群組的任何決定如下: (a) 響應於出現的耐受性數據來修改AZD6738*的劑量、每日劑量頻率或時間表以在給定的週期內增加、維持或減少AZD6738的暴露; (b) 如果研究者認為該劑量係被耐受的,則遞增AZD6738的劑量;或 (c) 如果研究者認為該劑量不被耐受,則以特定的時間表遞減AZD6738的劑量(針對高於20 mg的劑量)至先前更低的劑量水平(至多6名可評估患者的最大值)或至中間的更低劑量水平;或 (d) 如果研究者認為目前的時間表係非耐受的,則對紫杉醇劑量後停止用AZD6738治療的時間增加額外的天數,同時相應減少用AZD 6738的治療天數;或 (e) 基於出現的數據增加第一週期紫杉醇之前停止用AZD6738治療的時間; (f) 取決於出現的數據增加AZD6738的每日劑量頻率;或 (g) 取決於出現的數據減小AZD6738的每日劑量頻率Based on the data presented, any decisions made by the SRC to change the next cohort are as follows: (a) modifying the dose, daily dose frequency, or schedule of AZD6738* in response to emerging tolerability data to increase, maintain, or decrease exposure to AZD6738 over a given cycle; (b) escalate the dose of AZD6738 if the investigator believes the dose is tolerable; or (c) Decrease the dose of AZD6738 on a specified schedule (for doses above 20 mg) to a previously lower dose level (maximum of up to 6 evaluable patients) if the investigator believes the dose is not tolerated ) or to an intermediate lower dose level; or (d) if the investigator believes that the current schedule is not tolerated, add an additional number of days to the time to discontinue treatment with AZD6738 after the paclitaxel dose, with a corresponding reduction in the number of days of treatment with AZD6738; or (e) increasing the time to discontinue treatment with AZD6738 before the first cycle of paclitaxel based on emerging data; (f) increase the frequency of daily doses of AZD6738 depending on emerging data; or (g) Decrease daily dose frequency of AZD6738 depending on emerging data
在連續的群組之間可能發生對以下參數中的僅2種的改變: (h) AZD6738的劑量。 (i) AZD6738的每日劑量頻率。 (j) AZD6738的時間表。 然而,與先前最大耐受總週期劑量相比,總週期劑量或預測的Cmax增加不超過2倍。紫杉醇時間表和劑量係固定的。Changes to only 2 of the following parameters may occur between consecutive groups: (h) Dosage of AZD6738. (i) Daily dose frequency of AZD6738. (j) Timeline of AZD6738. However, the total cycle dose or predicted Cmax did not increase more than 2-fold compared to the previous maximum tolerated total cycle dose. The paclitaxel schedule and dose were fixed.
劑量限制性毒性( DLT ) :如果至多6名可評估的患者中的2名或更多名在一個劑量水平經歷DLT,那麼認為該劑量係不被耐受的並且劑量遞增停止。一旦不被耐受的劑量被確定,MTD將被確認為低於該不被耐受的劑量的先前的劑量水平或者將研究在該不被耐受的劑量和最後耐受的劑量之間的劑量。需要六名可評估的患者來確定MTD。 Dose-Limiting Toxicity ( DLT ) : If 2 or more of up to 6 evaluable patients experienced DLT at a dose level, the dose was considered to be intolerable and dose escalation was discontinued. Once the intolerable dose is determined, the MTD will be confirmed as a previous dose level below the intolerable dose or doses between the intolerable dose and the last tolerated dose will be investigated . Six evaluable patients were required to determine MTD.
DLT被定義為在第0週期(單一療法)和第1週期(組合)時間段的期間(即,從第0週期的第1天給藥直到第1週期的最後一天給藥)的任意毒性,這包括:
(a) 如下的血液毒性:
- 4級嗜中性白血球減少症(ANC < 500個細胞/mm3)持續超過連續4天
- 在任何持續時間內伴有發燒 ≥ 38.5°C和/或全身感染的3級噬中性白血球減少症(ANC ≥ 500至 < 1000個細胞/mm3)。
- 伴有出血的3級血小板減少症(25,000至 < 50,000/mm3)。
- ≥CTCAEv4 4級的任何其他確定的血液學毒性(可能需要重複以在缺乏臨床體征、症狀或其他異常調查時確定孤立性異常,即受懷疑的虛假值)。
(b) ≥ CTCAEv4 3級的非血液學毒性,包括:
- 實驗室異常(可能需要重複以在缺乏臨床體征、症狀或其他異常調查時確定孤立性異常,即受懷疑的虛假值)。
- QTc延長(> 500 msec)。
(c) 任何其他大於基線處的並且臨床上重大和/或不可接受的和不響應於支持性護理的毒性。
(d) 被SRC判定為DLT的任何事件,包括重大的劑量減少或遺漏。
(e) 排除的DLT:
- 任何級別的脫髮。
- 未充分治療的3級噁心和/或嘔吐和3級腹瀉(任何此類患者應該已經接受最佳止吐和/或止瀉預防和/或治療)。
- 明顯與AZD6738/卡鉑組合無關的任何毒性,例如研究中僅與疾病有關的或疾病相關的過程。DLT was defined as any toxicity during the period of Cycle 0 (monotherapy) and Cycle 1 (combination) time periods (ie, from dosing on Day 1 of
功效評估
:該研究評估了AZD6738在與紫杉醇組合給藥時在患有轉移性實體癌症的患者中的功效。藉由確定PFS和ORR,使用RECIST 1.1標準來評估患者對治療的反應。RECIST 1.1指南用於可測定的、不可測定的、靶和非靶病變以及客觀腫瘤反應標準(完全反應、部分反應、穩定疾病或疾病的進展)。在基線處使用腫瘤負擔的評估方法,在每次隨後的跟蹤評估時使用胸、腹部和骨盆的CT或MRI掃描。在基線評估後,藉由每8週(相對於第一劑量的日期)進行客觀腫瘤評估來評估對所有患者的功效,直到第40週,此時每12週進行評估直到如RECIST 1.1定義的客觀疾病進展。Efficacy evaluation : This study evaluated the efficacy of AZD6738 in patients with metastatic solid cancer when administered in combination with paclitaxel. RECIST 1.1 criteria were used to assess patient response to treatment by determining PFS and ORR. RECIST 1.1 guidelines are used for measurable, non-measurable, target and non-target lesions, and objective tumor response criteria (complete response, partial response, stable disease, or disease progression). Tumor burden assessments were used at baseline, and CT or MRI scans of the chest, abdomen, and pelvis were used at each subsequent follow-up assessment. Efficacy in all patients was assessed by objective tumor assessment every 8 weeks (relative to the date of the first dose) after the baseline assessment until
如果患者在進展前中斷治療(和/或接受隨後的癌症療法),那麼該患者將被繼續跟蹤直到如RECIST 1.1定義的客觀疾病進展。If a patient discontinued treatment (and/or received subsequent cancer therapy) prior to progression, the patient will continue to be followed until objective disease progression as defined by RECIST 1.1.
客觀腫瘤反應評估的分類基於RECIST 1.1反應標準:CR(完全反應)、PR(部分反應)、SD(穩定疾病)和PD(疾病進展)。相比於當腫瘤負擔處於最小(即,研究中以前記錄的最小直徑之和)時來計算靶標病變(TL)進展。在沒有進展時,相比於開始治療之前獲得的基線腫瘤測量值來計算腫瘤反應(CR、PR、SD)。Classification of objective tumor response assessments was based on RECIST 1.1 response criteria: CR (complete response), PR (partial response), SD (stable disease), and PD (progressive disease). Target lesion (TL) progression was calculated compared to when tumor burden was at a minimum (ie, the sum of the smallest diameters previously recorded in the study). In the absence of progression, tumor response (CR, PR, SD) was calculated compared to baseline tumor measurements obtained prior to initiation of treatment.
對於任何在基線處具有不可測量的疾病的患者,客觀腫瘤反應評估的分類基於RECIST 1.1反應標準:CR、PD和非CR/非PD。如果研究者不確定進展是否已經發生,特別是對NTL(非靶病變)的反應或出現新病變情況下,建議繼續進行治療直到下一個預定評估或更早(如果有臨床指征)並重新評估受試者的狀態。如果重複掃描確定進展,那麼初始掃描的日期將被宣佈為進展日期。For any patient with unmeasurable disease at baseline, classification of objective tumor response assessments was based on RECIST 1.1 response criteria: CR, PD, and non-CR/non-PD. If the investigator is unsure whether progression has occurred, especially in response to NTL (non-target lesions) or new lesions, it is recommended to continue treatment until the next scheduled assessment or earlier (if clinically indicated) and reassess Subject's status. If repeated scans determine progress, the date of the initial scan will be declared the progress date.
懷疑有新疾病的任何其他位置也應進行適當成像。如果執行計畫外的評估並且患者還未進展,則應在計畫訪視時儘量嘗試執行後續評估。為了在非靶疾病的基礎上實現‘明確的進展’,非靶疾病的整體水平必須嚴重惡化,以便即使在靶疾病中存在SD或PR的情況下,總體腫瘤負荷也已增加足以值得中止療法。一個或多個非靶病變的大小的適度地「增加」通常不足以證明明確的進展狀態。Any other locations where new disease is suspected should also be properly imaged. If an unscheduled evaluation is performed and the patient has not progressed, an attempt should be made to perform a follow-up evaluation at the planned visit as much as possible. To achieve 'definitive progression' on the basis of off-target disease, the overall level of off-target disease must be severely worsened so that even in the presence of SD or PR in target disease, the overall tumor burden has increased enough to warrant discontinuation of therapy. A modest "increase" in the size of one or more non-target lesions is usually not sufficient to demonstrate a definitive progression status.
在進展後,繼續跟蹤患者數週,如研究時間表所概述的(參見表1)。盡可能貼近地遵循評估時間表係重要的。Following progression, patients were continued to be followed for several weeks, as outlined in the study schedule (see Table 1). It is important to follow the assessment schedule as closely as possible.

使用合適的生物分析法來分析樣本以確定AZD6738和活性代謝物在血漿中的濃度和AZD6738在尿液中的濃度和紫杉醇在血漿中的濃度。在生物分析實驗室接收時,所有仍在目的分析物(即AZD6738或紫杉醇)的已知穩定性範圍內的樣本都將進行分析。此外,藥物動力學樣本可能已經進行進一步分析以便進一步研究藥物代謝物的存在和/或屬性。此類分析的任何結果將與臨床研究報告分開報告。The samples are analyzed using an appropriate bioassay to determine the plasma concentrations of AZD6738 and the active metabolite and the urine concentrations of AZD6738 and the paclitaxel concentrations in plasma. All samples still within the known stability range of the analyte of interest (ie AZD6738 or paclitaxel) will be analyzed upon receipt in the bioanalytical laboratory. In addition, pharmacokinetic samples may have undergone further analysis to further investigate the presence and/or properties of drug metabolites. Any results of such analyses will be reported separately from the clinical study report.
藥效學 :藥效學(PDc)生物標誌物係本研究的關鍵次要目標並且用於告知在具有AGC的患者中用AZD6738治療後ATR靶抑制的程度和持續時間。PDc生物標誌物分析還用於獲得患者中AZD6738 PK-PD關係的初始評估並確定與ATM狀態和對AZD6738治療的反應的任何回溯關聯。 Pharmacodynamics : Pharmacodynamic (PDc) biomarkers were a key secondary objective of this study and were used to inform the extent and duration of ATR target inhibition following treatment with AZD6738 in patients with AGC. PDc biomarker analysis was also used to obtain an initial assessment of the AZD6738 PK-PD relationship in patients and to identify any retrospective associations with ATM status and response to AZD6738 treatment.
生物標誌物: 對於該I期試驗,基於血液的PDc生物標誌物樣本的採集係強制的。收集外周血樣本並分析以對ATR途徑生物標誌物進行下游分析,在純化的外周血單核細胞(PBMC)樣本中,ATR途徑生物標誌物可以包括但不限於γ-H2AX、pCHK、pATR。如研究計畫中的詳述收集外週血(10 mL),如果訪視發生在週末,則波動為 +/- 1天。用於生物標誌物分析的血液、存檔的和鮮凍的組織的採集、樣本的運送和儲存的其他細節可在實驗室手冊中找到。 Biomarkers: For this Phase I trial, collection of blood-based PDc biomarker samples was mandatory. Peripheral blood samples are collected and analyzed for downstream analysis of ATR pathway biomarkers, in purified peripheral blood mononuclear cell (PBMC) samples, ATR pathway biomarkers can include but are not limited to γ-H2AX, pCHK, pATR. Peripheral blood (10 mL) was collected as detailed in the study plan, with fluctuations of +/- 1 day if visits occurred on weekends. Additional details on collection of blood, archived and frozen tissue, sample shipping and storage for biomarker analysis can be found in the laboratory manual.
對於所有患者,要求包埋在石蠟塊中的福馬林固定的腫瘤組織。如果還可以收集基線生檢樣本,則仍高度鼓勵取回存檔診斷腫瘤材料,以提供自診斷以來腫瘤如何演變的數據。接受來自原發性腫瘤或轉移性腫瘤的存檔樣本,但是來自原發性腫瘤的組織係較佳的。來自最近的生檢的組織係較佳的,其中患者具有來自多個時間點的存檔組織樣本。如果腫瘤塊不能提交,則接受新鮮製備的未染色的載玻片(最少10個,較佳的是20個)、來自存檔的腫瘤塊的4個微切片,然而腫瘤組織塊係較佳的。
收集10 mL外周血樣本以提供血漿用於循環腫瘤DNA,分析預測生物標誌物,並詢查遺傳改變的變化和對AZD6738治療具有抗性的潛在機制。在以下時間點收集用於ctDNA的血液樣本:治療前第0週期第1天、第1週期第1天和每個週期第1天、以及治療中止時。臨床試驗結果 Formalin-fixed tumor tissue embedded in paraffin blocks was required for all patients. If baseline biopsies can also be collected, retrieval of archived diagnostic tumor material to provide data on how the tumor has evolved since diagnosis is still highly encouraged. Archived samples from primary or metastatic tumors are accepted, but tissue lines from primary tumors are preferred. Tissue lines from recent biopsies are preferred, where the patient has archived tissue samples from multiple time points. If the tumor mass cannot be submitted, freshly prepared unstained slides (minimum 10, preferably 20), 4 microsections from the archived tumor mass are accepted, however tumor tissue mass is preferred. A 10 mL peripheral blood sample was collected to provide plasma for circulating tumor DNA, analyzed for predictive biomarkers, and interrogated for changes in genetic alterations and underlying mechanisms of resistance to AZD6738 treatment. Blood samples for ctDNA were collected at the following time points: day 1 of
為了使患者對於DLT評估係可評估的,他們必須在第1週期期間已經接受至少75%指定劑量的賽拉雷澤替博、或在相同時間段期間經歷了DLT。根據RECIST 1.1標準、使用電腦斷層成像每兩個週期評估腫瘤反應持續前10個週期,隨後每3個週期進行評估直到進展。In order for a patient to be evaluable for DLT assessment, they must have received at least 75% of the indicated dose of xelarazepate during Cycle 1, or experienced a DLT during the same time period. Tumor response was assessed every two cycles using computed tomography according to RECIST 1.1 criteria for the first 10 cycles and every 3 cycles thereafter until progression.
根據以上方案在臨床試驗中招募57名患者(33名黑色素瘤患者、15名胃癌(GC)患者、4名肉瘤患者、3名大腸癌患者、1名神經內分泌癌患者和1名肝細胞癌患者),包括從40 mg OD至240 mg BID的7個劑量群組。以AZD6738 160 mg BD和240 mg BD(第1-14天)的n = 6名可評估患者的每個群組中發生一例中性粒細胞減少症發熱的劑量限制性毒性(DLT)。根據方案,AZD6738的最大耐受劑量係240 mg BID(第1-14天)。57 patients (33 patients with melanoma, 15 patients with gastric cancer (GC), 4 patients with sarcoma, 3 patients with colorectal cancer, 1 patient with neuroendocrine cancer and 1 patient with hepatocellular carcinoma were enrolled in the clinical trial according to the above protocol ), including 7 dose cohorts from 40 mg OD to 240 mg BID. One dose-limiting toxicity (DLT) of neutropenic fever occurred in each cohort of n = 6 evaluable patients with AZD6738 160 mg BD and 240 mg BD (Days 1-14). According to the protocol, the maximum tolerated dose of AZD6738 is 240 mg BID (Days 1-14).
來自初始數據組,最普通的毒性(所有的起因、所有的級別)係厭食(n = 15,26%)、噁心(n = 15,26%)、白血球減少(n = 12,21%)和貧血(n = 11,19%)。51名患者係功效可評估的,並觀察到以下結果:1名完全反應(1.9%,黑色素瘤)、12名確定的部分反應(23.5%;2名胃癌,10名黑色素瘤,他們全部係在免疫療法後)、18名穩定疾病(35.3%)和20名疾病進展(39.2%)。來自劑量遞增的總確認反應率係25.5%。對黑色素瘤受試者觀察到的確定反應率(基於臨床研究者的評估)具體是30名患者中的10名或33.3%。From the initial data set, the most common toxicities (all causes, all grades) were anorexia (n = 15, 26%), nausea (n = 15, 26%), leukopenia (n = 12, 21%) and Anemia (n = 11, 19%). Fifty-one patients were evaluable for efficacy and the following outcomes were observed: 1 complete response (1.9%, melanoma), 12 confirmed partial responses (23.5%; 2 gastric cancer, 10 melanoma, all of whom were after immunotherapy), 18 had stable disease (35.3%), and 20 had progressive disease (39.2%). The overall confirmed response rate from dose escalation was 25.5%. The confirmed response rate (based on clinical investigator assessment) observed in subjects with melanoma was 10 out of 30 patients or 33.3%.
來自更新數據組,最普通的治療緊急不良事件(所有起因、所有級別)係貧血(n = 27,47%)和噬中性白血球減少症,包括嗜中性白血球計數減少(n = 24,42%)。不良事件的總結提供於表3中。在功效組中(57名接受至少一劑量的賽拉雷澤替博或紫杉醇的患者中),有1名完全反應(CR)(1.8%,黑色素瘤)、12名確定的部分反應(PR)(12/57 [21.1%];2名胃癌、10名黑色素瘤,所有黑色素瘤病例都已經接受先前的免疫療法)、18名患者具有穩定疾病的最佳反應(SD,31.6%)、22名患者具有進行性疾病(PD)和4名不可評估的患者。在數據截取時,仍有三名患者正在接受研究藥物。在患有黑色素瘤的患者的亞組(n = 33)中,ORR係33.3%(95% CI,18.0 - 51.8)並且DCR係60.6%(95% CI 42.1 - 77.1%)。黑色素瘤患者的中值PFS係3.60個月(95% CI 2.00 - 5.78)、中值反應持續時間係9.9個月(95% CI 3.7 - 23.2)並且mOS係7.4個月(95% CI 5.7 - 11.9)。沒有出現基線水平的LDH相關的反應,因為在具有高基線LDH的患者中觀察到反應,在黑色素瘤中這係負的預後指標,表明即使在具有差的治療結果的該組中也有益處(來自LDH > ULN的28人中有8名反應者)。也沒有出現PD-L1表現相關的反應(來自PD-L1表現 ≤ 5%的12人中有6名反應者)。而且,所有黑色素瘤的組織學亞型都觀察到反應,包括11名皮膚黑色素瘤中的3名、10名肢端黑色素瘤中的3名和11名黏膜黑色素瘤中的5名。對研究治療產生反應的黑色素瘤患者中的兩名對先前的PD-1免疫療法有反應;6名具有SD作為最佳反應並且3名具有PD作為最佳反應。From the updated data set, the most common treatment-emergent adverse events (all causes, all grades) were anemia (n = 27, 47%) and neutropenia, including decreased neutrophil counts (n = 24, 42 %). A summary of adverse events is provided in Table 3. In the efficacy group (among 57 patients who received at least one dose of xelarazepte or paclitaxel), there was 1 complete response (CR) (1.8%, melanoma), 12 confirmed partial responses (PR) (12/57 [21.1%]; 2 gastric cancer, 10 melanoma, all melanoma cases had received prior immunotherapy), 18 patients had best response with stable disease (SD, 31.6%), 22 Patients had progressive disease (PD) and 4 non-evaluable patients. At the time of data interception, three patients were still receiving study drug. In the subgroup of patients with melanoma (n = 33), ORR was 33.3% (95% CI, 18.0 - 51.8) and DCR was 60.6% (95% CI 42.1 - 77.1%). For melanoma patients, median PFS was 3.60 months (95% CI 2.00 - 5.78), median duration of response was 9.9 months (95% CI 3.7 - 23.2), and mOS was 7.4 months (95% CI 5.7 - 11.9) ). Baseline-level LDH-related responses did not occur, as responses were observed in patients with high baseline LDH, a negative prognostic indicator in melanoma, suggesting benefit even in this group with poor treatment outcomes (from 8 of 28 people with LDH > ULN were responders). There were also no responses related to PD-L1 performance (from 6 responders out of 12 with PD-L1 performance ≤ 5%). Furthermore, responses were observed in all histological subtypes of melanoma, including 3 of 11 cutaneous melanomas, 3 of 10 acral melanomas, and 5 of 11 mucosal melanomas. Two of the melanoma patients who responded to study treatment responded to prior PD-1 immunotherapy; 6 had SD as best response and 3 had PD as best response.
基線血漿的基因組分析(27名患者)顯示了在黑色素瘤患者中NF1體細胞突變和激活性NRAS突變的富集(分別是6/18和4/18)。在三名疾病控制的患者中觀察到白介素-12水平的週期性變化,這能反映反應機制的免疫學組分。Genomic analysis of baseline plasma (27 patients) showed enrichment for NF1 somatic mutations and activating NRAS mutations in melanoma patients (6/18 and 4/18, respectively). Cyclical changes in interleukin-12 levels, which could reflect the immunological component of the response mechanism, were observed in three disease-controlled patients.
